How to list all the users that have access to a directory?
4
When I do ls -al, I see that "users" have access to a particular directory. How do I see what users have what access to these directories?
$ls -al
drwxrwxrwt 7 root root 4096 Mar 9 23:37 .
drwxr-xr-x 5 root root 4096 Feb 22 14:28 ..
drwxrwxrwx 65 myname users 4096 Feb 22 20:08 tools
-rwxr-xr-x 1 myname users 3832976 Jan 27 13:39 pfiles
drwxr-xr-x 2 myname users 4096 Jan 23 07:57 nfiles
drwxr-xr-x 4 myname users 4096 Aug 1 2014 dfiles

when you set the linux permissions like your example. Others can read/execute your directory.Because your linux permissions setting was rwx - rx -rx or 755.

to put a finer point on what supriady said, everyone that can log in to the system can see those files/directories (assuming they can get to the parent directory).

users is a group, so the members of that group and all of the other groups is available in /etc/group.
The ArchWiki has an excellent page on file permissions and attributes.

Strange, "users" should be an invalid group, then, and the GID would be shown instead of the name. Which distribution are you on?
